How to raise poinsettia, a complete solution to the breeding method and technology of poinsettia

Where do you think poinsettia flowers grow? If your answer is at the top, it would be wrong, because the leaves growing at the top are red or white, which are often mistaken for flowers, and poinsettias usually grow in the middle of the leaf bundle. Flowering December to February, poinsettia flowers are mostly red. So it looks very festive. Poinsettia display picture

Poinsettia has many functions, can be used to make food, can also be used to make wine, not only that, poinsettia also plays a unique role in medicine, poinsettia can be used as a medicinal plant to promote blood circulation and reduce phlegm, bone grafting and swelling. Poinsettia silently let everyone watch at the same time, but also bring more benefits to everyone. The picture below is a delicious dish made by poinsettia. Poinsettia shows the breeding method of poinsettia is actually not difficult, generally speaking, when we plant poinsettia, we should be familiar with its growth habits. Poinsettia likes to grow in a moist and ventilated environment and does not have much resistance to low temperature. therefore, when planting, we must give it to adapt to the temperature to avoid too strong sunlight, but also pay attention to the lack of light. Poinsettia shows that poinsettia does not have high requirements for soil, basically fertile sandy soil, it can also grow very well, in the hot summer, we should replenish moisture, watering should be moderately dry and wet, if there is stagnant water in the basin, we should deal with it in time so as not to cause the root of poinsettia to rot. Poinsettia cutting part of the data above is a poinsettia cutting 16 days after some data display map, in poinsettia propagation is mainly cutting, there are mainly hardwood cuttings and tender wood cuttings, in the cutting period, we should pay special attention to some things not conducive to growth, pay attention to shade, moisturizing, prevent leaf curl, rooting after half a month, can be transplanted on the pot after a month.

How to raise poinsettia, how to raise poinsettia

Poinsettia blossoms when all flowers wither in winter. Mr. Guo Moruo once made a moving description and enthusiastic praise of the beautiful and lovely poinsettia: "to the number of cold winters, thousands of flowers are scattered, in a bleak, poinsettia still maintains its red heart, no matter how cold the wind is, no matter how bullied by frost and snow, it is always so red, never fade …... no, no, no. This is exactly what we need most, the red of a pint. "

At present, poinsettia has become an important potted flower in commercial production in Europe, America and Japan. Poinsettia can grow into shrubs 3 to 4 meters high in the open air, with red flowers, creating a very eye-catching and moving scenery. For example, poinsettia as a cut flower, with 2 or 3 carnations and several silver willows in a bottle, placed on the desk, is better than honeysuckle, and has a natural interest that complements each other.

Poinsettia, also known as poinsettia, is also known as Christmas flowers because it blossoms at Christmas. Is an evergreen shrub of Euphorbiaceae. It is 1 to 3 meters high. The stem is erect and contains white milk. The old stem is woody and yellowish brown; the tender stem is erect, smooth, herbaceous, hollow

Bright green. Leaves ovate-elliptic to broadly lanceolate

Beautiful and gorgeous

Shaped, alternate, upper leaves bract-like, red. Inflorescences terminal. The flowers are small and not ornamental. Involucral bracts are light green, each bract has 1 or 2 large yellow glands.

Common varieties are poinsettia, scarlet poinsettia, double poinsettia, globular poinsettia, spotted leaf poinsettia.

Poinsettia originated in Mexico, Central America and other places. Sex likes a warm, moist and sunny environment. Afraid of bright light, not resistant to cold, afraid of frost. Need strong permeability, good drainage, loose and fertile soil.

The basin soil should be loose, fertile and highly permeable sandy soil. The quality of the soil directly affects the growth of poinsettia. It can be made by mixing culture soil, rotten leaf soil and sand, or by combining peat soil, carbonized rice husk and coarse river sand with a ratio of 3: degree to degree. The slightly acidic soil is better, and the addition of appropriate amount of calcium and magnesium fertilizer can make the red Xun piece more bright.

The suitable temperature for growth is 18-25 degrees, and the winter temperature should not be lower than 10 degrees, otherwise the basal leaves are easy to turn yellow and fall off, resulting in the phenomenon of "foot removal". When the temperature rises in spring, branches can continue to sprout from the stem.

Poinsettia is a short-day plant. Sufficient sunlight is needed during the growth period of stems and leaves to promote the rapid growth of stems and leaves. In order to make the bracts turn red ahead of time, the daily light should be controlled within 12 hours to promote flower bud differentiation. If the light is 9 hours a day, the bracts can turn red after 5 weeks. But it needs to be moved to semi-shade in summer.

Sensitive to moisture, afraid of stagnant water. During the growing period, if the water supply is sufficient, the stems and leaves grow rapidly, sometimes the phenomenon of elongation of internodes and narrow leaves occurs; on the contrary, the lack of water in the basin soil or sometimes dry and wet will cause leaf yellow shedding. Therefore, watering poinsettia should be dry and wet all one's life, in order to keep the basin soil wet to dry.

I like fertilizer very much, but the concentration of fertilizer should not be high. Liquid fertilizer is applied every 10 days during the growing period. Two weeks before flower bud differentiation, a spoonful of resin film slow-acting fertilizer with a ratio of 14: 4: 4 was added to each plant to supplement the deficiency of soluble fertilizer. The concentration of fertilizer should be reduced by half in winter.

It is commonly used to propagate by means of protection. Hardwood or softwood cuttings can be used, but softwood cuttings are often used.

Cutting propagation: from April to May, select annual lignified or semi-lignified sturdy branches, 10 cm long, cut off the leaves on the cuttings, wash the milk from the cut, dip the cut in grass ash, and cut it in fine sand after drying. At 25 degrees at room temperature, it will heal and take root 14-18 days after cutting.

Softwood cuttings: when the tender strips grow to 6-8 leaves, take a 6-8-cm-long shoot with 3-8-node shoots, cut them flat under the node, remove the large leaves at the base, and immediately throw them into clean water to prevent milk outflow, and then cuttings, 'and keep the substrate wet, about 20 days can take root. As long as the temperature is suitable, it can be carried out all the year round, and the cutting is the most suitable when the temperature is 15 ~ 8 degrees.

It is very important to control humidity before rooting at the initial stage of cutting, and it even takes a while to spray.

Fog once, in order to avoid the loss of water in leaves and increase the survival rate.

Leaf spot, gray mold and stem rot mainly occur, which can be sprayed with 1000 times of 70 "methyl topiramate wettable powder.

Poinsettia grows faster and needs pruning and shaping. In order to control plant height, topping, twig head and growth inhibitor are commonly used, and the first two are commonly used in families.

The top was cut off twice during the growth process, the first in late June and the second in mid-August. The height of the truncation is determined according to the need.

Quzhi Pantou was carried out in May, leaving 3-4 branches per plate. With the elongation of the stem, the twigs were tied up with a thin bamboo frame, and the bracts stopped when they appeared. Curved branches should be timely, otherwise the branches are strong and easy to break, affecting the state of the plant.
